This is a sequence hold, not necessarily are they aborting the whole thing just yet.

Any idea where the transients are being tracked to?

They aborted the sequence, not the attempt. They'll either recycle to the terminal count or scrub.

Like Robotbeat said, holding no abort get

A rule of thumb: if you see the vehicle starting to vent again after around T-40 sec, it's a safe bet the count was aborted.

If they go again, expect a recycle to T-13:00 or so.

Notable point is that would have resulted in a scrub on launch day due to the instant launch window. So it's good to get this out of the way now.

To me it looked as if the upper stage never stopped venting.

Do we know if it was an automated or manual hold?

Disabling the prop systems.

noticed the lox never closed and pressurized. When does this happen in the count?

Think this was for Dragon since we don't hear LV comm

No info on the plan yet.

I noticed a lot of venting, just before the hold, from the second umbilical down at the strong back. Normal?

Phew for a few moments it didn't seem like the livestream was working for me. Works now though.

I believe pressurization occurs at T-40 seconds.

On a related note- can we presume continued venting means no prop offload so far, so not aborted *yet*?

Clocks have reset to 13 minutes

Chris Bergin · « **Reply #119 on:** 04/30/2012 07:13 pm »

So clearly there is an opportunity to recycle - pending the data review on giving this another shot today.
